Answer:
from my understanding the answer is 175.80
Step-by-step explanation:
Answer:
2.33
Explanation:
First find the mean:
1 + 10 + 7 + 6 + 4 + 8 = 36
36 / 6 ( there are 6 total numbers) = the mean is 6
Then subtract the mean from each number:
1 - 6 = -5
10 - 6 = 4
7 - 6 = 1
6 - 6 = 0
4 - 6 = -2
8 - 6 = 2
(don't worry about the negatives)
5 + 4 + 1 + 0 + 2 + 2 = 14
14 / 6 ( again, there are 6 total numbers) = 2.33
option 3.................
In solving this type of problem always look for the person you don't have any information about in this case it's Eve therefore Eve is X, Justin has $7.50 more than Eve, therefore
X+$7.50 is Justin and Emma has $12 less than Justin, therefore subtract $12 from Justin X+$7.50-$12, since the total amount is $63 add all the numbers and equal them to $63.
x+7+x+7.5-12+ x=63
3x+3=63
3x=60
x=20
Plug in the x for each person
therefore Eve=$20
Justin=$20+$7.50= $27.50
Emma has $12 less than Justin therefore $15.50
Add all the money and it equals $63
Answer:
y = 1/5x + 9/5.
Step-by-step explanation:
x = -3 + 5y - 6
5y - 3 - 6 = x
5y - 9 = x
5y = x + 9
y = 1/5x + 9/5.
Hope this helps!
